384GB DDR5 ECC RDIMM kit for Supermicro H14DSH

This 384GB kit contains eight 48GB DDR5 4800 modules built to the exact 2Rx8 registered ECC specification the H14DSH memory controller expects. It is intended for administrators expanding memory capacity in compatible Supermicro servers running production workloads.

Check motherboard manual for population rules

Verify the H14DSH manual for approved DIMM population order, maximum supported capacity per slot, and any BIOS version requirements before installation. The kit uses 288-pin RDIMM form factor; ensure no UDIMM or SODIMM slots are populated by mistake.

Lifetime replacement warranty

The bundled lifetime warranty provides module replacement if a defect appears during service. Free US-based technical support assists with configuration questions, helping confirm correct population order and troubleshoot any recognition issues.

Questions about this item

Does the kit include all eight 48 GB DDR5 RDIMMs or must any modules be purchased separately?

The kit contains eight 48 GB DDR5 RDIMM modules for a total of 384 GB, so nothing else is required to fill all eight slots.

Should I choose the 384 GB 8 × 48 GB DDR5 4800 CL40 kit or a different capacity for my Supermicro H14DSH?

Select this 384 GB kit when the board’s qualified-vendor list approves eight 48 GB 2Rx8 registered ECC DIMMs at 4800 MT/s; otherwise follow the manual’s supported population table.

What does the 4800 MT/s rating mean once the memory is installed in the server?

The modules will run at 4800 MT/s with CL40 latency at 1.1 V, delivering the full PC5-38400 bandwidth the memory controller expects when all slots are populated.
